Johnson, a fourth-round pick of the Cowboys in 2012, has yet to suit up for an NFL regular-season game. In fact, he has only played in two preseason games and has been injured both times. Nate Livings, who had a knee scope early in training camp, had also been placed on IR.

Johnson started the preseason opener vs. Miami in the Hall of Fame Game on Aug. 4. He played rather well in the first quarter before suffering a sprained foot in the second quarter. Last year, Johnson played just one preseason game before suffering his second hamstring injury of the offseason. Later in the regular season, Johnson was in the game plan to make his NFL debut and sustained yet another hamstring injury.

While Johnson was placed on IR, he’s one of three more 2012 draft picks not on the 53-man roster, along with Coale and Caleb McSurdy, a seventh-round pick who missed all of last year with a torn Achilles.
